Reality TV star Ali Lohan has been round and about the party strips of Hollywood so frequently her mom Dina’s parenting skills are now being questioned.

Dina Lohan of course denies that she’s being negligent of looking after her daughter’s behavior, and says she devotes her life to her children.

“Ali is in a home-schooling program. She’s never been pulled out of school,” Dina states in an exclusive interview with PEOPLE magazine. “It’s the same home-schooling program that Lindsay was in since the tenth grade. It’s a wonderful program that many celebrities are enrolled in.”

Addressing the reports that Ali is fast becoming a certified party animal, Dina says that her daughter is working very hard, not just in recording and her fashion line-Ali’s been busy providing utmost moral support for her older sister Lindsay.

The older Lohan has just finished posing ala Marilyn Monroe for the cover of Spanish Vogue, and is focusing her attention on her spray tan line-which is reported to having sold more than 100,000 units at Sephora in just one day.
